1. Clamping Screw
Tin-plated brass screw and brass nut secures the bolted tee conductor contact with the bushing
2. Insulation
Moulded EPDM insulating rubber is formulated and mixed in-house to ensure high quality
3. Basic Insulating Plug
Moulded epoxy part has a threaded metal insert to accept the clamping screw
4. Capacitive Test Point
Capacitive test point provides means to check circuit status.
5. Rubber Cap
Moulded EPDM conducting rubber cap protects and earths the test point during normal operation
6. Internal Screen
Moulded EPDM conducting rubber screen controls electrical stress
7. Capacitive Test Point (Optional)
Capacitive Test point provides a means to check circuit status. A moulded EPDM conducting rubber cap provides a watertight seal.
8. Stress Relief
The configuration of the outer screen and the cable adapter provide cable stress relief
9. Cable Adapter
The sized opening provides an interference fit to maintain a watertight seal and provides the initial cable stress relief
10. Earthing Eyes
Moulded into the external screen for connection of an earthing wire
11. External Screen
Moulded EPDM conducting rubber provides protective deadfront shield.
12. Conductor Contact
Inertia welded bimetallic compression or mechanical (shear bolt) lug accepts copper or aluminum conductors.

The complete kit includes: moulded tee housing, cable adapter, conductor contact, insulating plug, rubber cap, clamping screw, lubricant, wipers and installation instructions.
To order a 42 kV bolted tee connector, use the Catalog Number
Section Guide, on page 4 and select the cable insulation range from Table 2, which gives you the best centering of the insulation diameter and then select the conductor size from Table 3.
Ordering Examplee: For a 36 kV drain wire shielded cable with a 500 mm2 aluminum conductor, 44 mm core insulation diameter and a DIN style crimp connector in a single-phase kit with a test point, including the cable sealing kit, specify
DTS1242FU500N1T1 .
